To whom it may poncewt:` i v d -Be it known that I, GQTTERIED AUGUST H.

l HERTZER, otvWaterford, in the county of Oakland,

`and State of Michigan, have-invented a new and useful Improvement in RailJoints; and VI` do declare that the following isa true and accurate description thereof', reference being had to the accompanying drawings,

and to the letters Vof reference' marked 4thereon, andv being a part of this specification, .in which. i Figure l is aplan view-of my improved joint';

j VFigure 2 is a cross-section ofthe same, on the line :ciu iig. 1;;and

1`. Figures 3 and'4 are planviews'of the under sides Like letters refer t like parts in each figure. The nature of this invention relates to an improvement vin the/construction of joints' for railway-bars,

and consists in a peculiar arrangement of bolts in a chair, `and in the employment of peculiar cups recessed to receive'the lnuts of said bolts, fol-preventing ftheir turning 4and loosening from the vibration of passing trains. i In the drawings A represents a cross-tie, on iwhich is secured thechairB, byspikes b. r

- This chair isforredwith a cheek-piece, B', which U, on its outer side. v

Projecting throughfrom the inner side of the rail,

.projects lun'der the head, against the web of thev rail 'through the cheek-piece B', are two or morev fish? bolts, D. i

On their threaded endslare nuts d, which draw the Vrail to the cheek-piece ofthechair. i E is a slotted stud, projecting from Vthe cheek-pie`ce between the fish-bolts. l

F is a lock-plate, having n n, opening by whichit is 0n i-tsunder side are two rectangular recesses, j,

corresponding inlsize andposition 'to the nuts dso that when the plate is placed in position, these nuts will enterjthe recesses andbe prevented from turning. 4

The' piates are held in place by a key of sheet` metal, e, pressed through the slot in the stud and bent, to prevent withdrawal. v

On the inner side of the rail, two4 bolts, G, and a stud, H, yproject upward from the chair, 4each bolt ,being provided with a nut, y.

I is a clamp, which lies on the chair, so' formed as to embrace the lower part of the web of the' rail and its foot.

It is also provided with proper' openings, to allow it to be slipped to its seat on the bolts and studs, where l itis secured by the nuts g. y

J is a lock-plate, similar in construction to that already described, and is secured in place by a'key, j, passin'g through a slot inthe stud H. e v

The tie A is sunk the thickness of the chair B, be

low the plane of th'eother ties..

u It will clearly be seen that, with a joint-thus areranged, the lamination of the ends 'of therails is entirely obviate'd, and that its eficiency is not liable to be impaired by reason of the loosening of the nuts,

which is preventedby the employment ofthe lock` plates. s

As the chair, clamp, and lock-plates may be con lstructed of cast-iron, the cost of the joint will be com# paratively small.

-What I claim as my invention, and desire to secure p by Letters Patent, is.- v

The chair B B', provided with the stud E, in combination with the clampI, provided with the stud H, and with the b'olts D and G, provided with nuts l and g, and with the lock-plates Fand' J, and lkeys e and. j arranged to operate as and for the purposes above Ahet forth.
